About Marathon Vert de Rennes
Rennes Green Marathon
The Rennes Green Marathon is a major running race organized every autumn in Rennes, Ille-et-Vilaine (Brittany). A solidarity and ecological race, it combines sporting effort with a concrete environmental commitment: for each participant, trees are planted in partnership with the Yves Rocher Foundation (2026 commitment: 2 km covered = 1 tree planted). In fourteen editions, the event has contributed to the planting of over 1.7 million trees.
Several races for all profiles
The event takes place over two days, Saturday evening and Sunday morning. On the program: the marathon (42.195 km), the four-person relay marathon, the duo marathon, a nocturnal 10 km, a 5 km women's race, and a family walk. The course, entirely urban and known for being very fast, runs through the streets of central Rennes, starting from Mail François-Mitterrand and finishing on Esplanade Charles-de-Gaulle.
An unmissable Breton event
Supporting the Brittany Marathon Championship and holding an international label, the Green Marathon has established itself as one of the major running events in the West of France. The festive atmosphere on Saturday evening, the challenge on Sunday morning, and the ecological dimension make it a unique event in the calendar of French races.
